Charnia wardi Trepassia is a 579 million-year-old fossil[1] of Ediacaran rangeomorph.

It was first discovered by Guy M. Narbonne, a professor at Queen's University in Ontario, Canada and colleagues in 2009.

[3] The generic name is taken from the French word, trépassés, which translates to "those that have departed forever" (or "corpses") and honors the Trepassey community in Newfoundland.

The adult specimens of Trepassia had substantial thickness, shown by the cylindrical cross-section of the frond.

[2] The suspension-feed strategy of Trepassia wardae was that it used its long, slender petalodium for continuous feeding at all heights above the sea floor.
